- •
The Miocene monzogranite porphyry (MMP) has higher fO2 and water than the Eocene monzogranite (EG).
- •
The decompression and discharge of SO2 through Linzizong volcanism reduced the fO2 of the EG.
- •
The water released by metamorphic dehydration reactions increased the water contents of the MMP.
- •
Subduction metasomatism and metamorphic dehydration controlled the genesis of post-collision porphyry deposits in Tibet.
